Part Verification and Datasheet Update

Thought for 6 mins 46 sec

I can take care of the part audit and metadata cleanup for this part project.

Here’s the current audit snapshot, using the datasheet-sync workflow as the reference process for part verification and property updates :

Current state

Table

Category	Findings
Project properties	Present: `Manufacturer Part Number = MCP4431-103E/ST`, `Designator Prefix = U`
Missing project metadata	No `Datasheet URL`, no `Manufacturer Name`, no package/case property, no explicit part type, no richer description found
Symbol pin count	20 terminals present
Footprint pad count	20 pads present
Package evidence in project	Footprint asset `MCP4431-103E_ST.kicad_mod`, 3D model `TSSOP20_MC_MCH.step`
Part family evidence from official/vendor pages	Quad I2C digital potentiometer, 20-lead TSSOP, -40°C to +125°C

What looks correct

Table

Check	Status
Pin count vs footprint pad count	Looks consistent at 20 ↔ 20
Package style in project	Looks consistent with TSSOP-20
Main pin names present	The project includes P3A, P3W, P3B, HVC/A0, SCL, SDA, VSS, VDD, NC, *RESET and the four potentiometer channel groups

Mismatches / gaps I found

Table

Area	Issue
Datasheet property	Missing
Project metadata	Manufacturer, package/case, part type, and description appear incomplete/missing
Pin typing	All terminals currently have `Pin Type = Unspecified`, including VDD, VSS, SCL, SDA, and NC
Pin descriptions	No pin descriptions were visible on the terminals
Datasheet cross-check completeness	I found the official Microchip product page, but I have not yet confirmed the exact canonical PDF URL from Microchip itself, so the final pin-by-pin textual verification against the official PDF is still pending

Key specs identified so far

Table

Spec	Value
Device type	Quad digital potentiometer
Interface	I2C
Variant	Volatile
Resistance option	10 kOhm (`103`)
Package	TSSOP-20
Temperature range	-40°C to +125°C

The next step is to populate the missing datasheet/property metadata and then normalize the terminal metadata so the symbol matches datasheet intent exactly, which is the recommended flow for part-project verification .
